The major problem in the treatment of morbidly obese children is the long term maintenance of the reduced weight. Maintenance-focused interventions have not been studied enough in adolescents with morbid obesity, neither in regard to conservative methods of weight reduction, nor in regard to bariatric surgeries.

This study will investigate the effectiveness of an integrative, multi-disciplinary inpatient program for promoting long-term weight maintenance in children with morbid obesity. The program will be studied in two perspectives: as a conservative treatment, as well as an 'envelope' for bariatric surgeries including a pre-operational preparation phase and a post-operational follow-up.

The investigators hypothesize that program participants will maintain weight significantly better than the proportion known in the literature.

Life habits will be assessed using a semi-structured interview designed easpecially for the purpose of the current study. The interview includes questions about eating behaviors, family life style, living arrangements, patterns of food consumption and availability etc.

The clinical features of morbid obesity and symptoms of other eating disorders are assessed using a semi-structured clinical interview based on and adaptation of the well-establised Morgan-Russel Scale.

Detailed Description:

Background: The major problem in the treatment of morbidly obese children and adolescents is not weight reduction itself, but the long term maintenance of the reduced weight. Treatment of morbid obesity has a dual goal: Immediate relief for the obesity-related physical symptoms (by moderate weight reduction), and prevention of relapse by encouraging weight maintenance. Without maintenance-focused interventions, morbidly obese children are prone for repeated weight gains that can induce further complications and undermine therapeutic efforts. Maintenance-focused interventions have not been studied enough in adolescents with morbid obesity. An alternative solution for the conservative approach described above is based on bariatric surgeries. These are currently limited in adolescents due to insufficient evidence regarding pre- and post-operational interventions for long term weight maintenance.

Goals: The study is designed to investigate the effect of an integrative, multi-disciplinary program for children and adolescents with morbid obesity. The program includes interventions for moderate weight reduction and for long term weight maintenance. The program is based on a year-long treatment continuum. The different phases of this continuum include a short hospitalization, intensive day treatment program, and weekly follow up. The program is also based on intensive work with parents, with emphasis on familial change of life habits. The program will be studied in two perspectives: as a conservative treatment, as well as an 'envelope' for bariatric surgeries including a pre-operational preparation phase and a post-operational follow-up.

Hypothesis: The proportion of program participants who will decrease their weight and maintain it for at least one year will be significantly higher than the proportion known in the literature. This finding is expected among participants in the 'conservative' program as well as among participants who will undergo bariatric surgeries.

Method: the study will take place in a child and adolescent psychiatric unit located in a general children hospital, in cooperation with pediatric and endocrinology units. Participants will undergo short hospitalization focused on acute relief of obesity related complications and as a pre-operational preparation for those participants who are designated for surgery. All participants, whether designed for operation or not, will continue participation in a year long day program focused on weight maintenance and acquisition of healthy life habits. Study design will include 4 assessments of psychical and psychological measures: pre-hospitalization screening, admission, 4-month follow up, 1-year follow up. At those assessment points, both children and parents will be assessed.

Criteria

Inclusion Criteria:
